Yes, this debate format is nice, but a little bit tight, if you know what I mean?

Brexit's Disadvantages:

Most Foreign Direct Investment comes from the EU. UK's FDI is worth 1 trillion [1]. Foreign investors like investing in the UK because it gives them easy access to the EU's single market (which means less borders in moving goods, less tarriffs, and more profit). Brexit makes it harder for UK to trade with EU. Deals can be made but will probably not be as good as it was before Brexit.

Any deals made, is likely to be complicated. The leaders of the EU have already said that in order for UK to access the single market, it must allow free movement of EU workers (for them to easily immigrate to the UK). [2]

Brexit means EU workers may not meet requirements for working in the UK, especially filling out the infamous UK visa test for non-EU citizens. About 3/4 of EU workers would fail this test, those in the primary and secondary sector (farming, hotel staff etc.). [3]

It's not just a problem of foreign workers. It's also the UK's own workforce, which relies on the EU as well. Being out of the EU means British workers need to apply for a work visa to work abroad. [4]
